Habitat valuation methods are most often developed and used to prioritize candidate lands for conservation. In this study the intent of habitat valuation was to inform was to inform the decision-making process for remediation of chemical contaminants on specific lands or surface water bodies. Methods were developed to summarize dimensions of habitat value for six representative aquatic and terrestrial contaminated sites at the East Tennessee Technology Park (ETTP) on the US Department of Energy Oak Ridge Reservation in Oak Ridge, TN, USA. Several general valuation metrics were developed for three broad categories; site use by groups of organisms, site rarity, and use value added from spatial context. Examples of...

This dataset depicts known contaminated sites under the jurisdiction of Canada's federal agencies and consolidated Crown corporations, including non-federal sites for which the Government of Canada has accepted some or all financial responsibility. A contaminated sites is defined as "one at which substances occur at concentrations (1) above background (normally occurring) levels and pose or are likely to pose an immediate or long term hazard to human health or the environment, or (2) exceeding levels specified in policies and regulations." (http://www.tbs-sct.gc.ca/fcsi-rscf/home-accueil.aspx?Language=EN&sid=wu1281891127). This dataset was created by the Conservation Biology Institute using publicly available information...

The Sediment-Contaminant Database for the Upper Mississippi River System contains information from a total of 3950 analyzed sediment samples, including 2697 from the Mississippi River, 440 from the Illinois River, and 813 from tributaries. These samples were collected during 1974 through 2000, with 262 samples from the 1970s, 2168 from the 1980s, 1518 from the 1990s, and 2 from the year 2000. The database contains data on metals, metalloids, nutrients, polynuclear aromatic hydrocarbons, insecticides, herbicides, fungicides, industrial compounds, sterols, petroleum-related compounds, and polychlorinated biphenyls in three types of samples: bed sediment (86.6% of the samples), sediment trap (1.8%), and pore water...

ICIS-NPDES is an information management system maintained by the Office of Compliance to track permit compliance and enforcement status of facilities regulated by the National Pollutant Discharge Elimination System (NPDES) under the Clean Water Act (CWA). ICIS-NPDES is designed to support the NPDES program at the state, regional, and national levels.Active facilities are those currently in operation. Major/federally-reportable are facilities for which states must submit compliance and enforcement data to EPA. Under the Clean Water Act, a major facility is any NPDES facility or activity classified as such by the regional administrator, or in the case of approved state programs, the regional administrator in conjunction...
